MEAN FOB COUNTER ROLLING A. CIGARETTE PAPER Application filed November 17, 1927, Serial N'o.'283,937, and in Germany November'26, 1926.

Cigarette shells or paper cases with mouthpieces are formed in well known manner by inserting into the cigarette shell from one end a so-called mouth-plece spiral. Such spirals before being inserted in the shell are coiled to small diameter and after being inserted and released tend to expand. As the spirals are formed of a spirally coiled stiii' paper strip the outer coil of the spiral does not lie 10 closely against the cigarette paper shell. To

sult is not always satisfactorily obtained by means of such known counter-rolling devices. The shellduring its passage between the counter-rolling surface and the roller or the like is as it were neglected'and some shells are more counter-rolled than others and some of the shells-pass through the counter-rolling device withouthaving been subjected to the required treatment.

By mounting the cigarette shell in accordance with this invention on a freely rotatable roller and rolling such roller over a counterrolling surface then (assuming the correct selection of the feed movement of the roller and that the direction of-rotation is correct) the shell must of necessity be subjected to the rolling movement and the spreading of the mouth-piece spiral must be effected.

Under this method each separate shell is subjected to a counter-rolling operation with certainty; the shell is positively held in the,

correct position and it is smoothly guided through the counter-rolling device without danger of displacement and consequent dam-- age to the shell.

My new method may be performed by means of a device in which the cigarette shells a plunger for each pocket, each plunger being provided at one end with a freely rotatable roller, the plungers being adapted to rotate in connection with the drum and their rollers arranged to roll over a counter rolling surface, disposed around the drum, during certain periods of the rotation of said drum.

The device is arranged to permit delivery of the finished counter rolled shells to .an endless belt or the like directly from the drum without the need for any specially controlled grippers or the like.

The accompanying drawings illustrate the invention by way of example. In these drawings. Figs. 1 and 2 show a vertical longitudinal section and a plan View respectively of another modification of the arrangement of the new counter-rolling device in side elevation or vertical transverse section;

Referring to the embodiment illustrated in Figs. 1 and 2 the cigarette shells lprovided at one end with an inserted mouth-piece spiral and delivered from the cigarette-shell making machine (not shown) are fed by means of a gripper 2 through a channel or passage 3 to said device. The gripper 2 consists of a rake, the tines of which project from beneath through longitudinal slots in the walls of the channel and are located behind the cigarette shells 1. The rake is carried by a support 4 which is mounted on the crank pin 5 of a crank 6. The rod shaped end 7 of the support is longitudinally movable in a guide which is adapted to rock about a transversepivot 9. The rake 2 is thus upon rotation of crank 6 in direction of the arrow given such a movement that the ends of its tines describe the closed curve .shown by a dotted line in Fig. 1; In consequence the tines push the shells 1 forward in the channel 3 and deliver them finally to the counter rolling channel 10. Such counter-rolling channel is formed in known-manner by a rotating-roller 11 and a curved counter-rolling surface 12 concentric therewith and suitably spaced therefrom. The shell 1 is guided through the gap between the periphery of the roller 11 and the counter-rolling surface 12 and is thus counter-rolled in known manner.

In accordance with the present invention the shell 1 leaving the counter-rolling channel is delivered to the upper flight of an endless feed band 13 which is guided over the pulleys 14 and 15 and moves in the direcconcentrically of the drum shaft. In these orifices are guided shafts 21 which carry at theirends rollers 22 and which are provided at their opposite ends with reduced portions 23 of circular cross sections. On these reduced portions are mounted freely rotatable rolls 24. Around the portions of the shafts 21 on the same side of disk 20 as the rollers 22 and between said rollers and said disk are mounted coiled springs 25 which tend to press the shafts with the rollers 22 against a stationary cam disc 26 which is secured to a stationary bearing 27.

The supp with the drum 17 and the stationary cam disc 26 causes the shafts with the ends carrying the rolls gradually to enter the pockets 18 on the drum 17 and to enter the cigarette shells located in such pockets. The device is naturally so disposed that the rolls 24 enter the mouth-piece ends of the shells, the rolls being of aflength corresponding to the length of the mouth-piece spirals.

Around the drum is mounted a counterrolling surface, for instance a casing 28, which partly embraces the drum, the distance of the casing from the drum being such that Q the rolls 24taking part in the rotation of the drum come in contact with the inner wall of the casing and roll around it. The mouthpiece ends of the cigarette shells fitted over the rolls are thus counter-rolled and the outer coils of the mouth-piece spirals are pressed against the walls of the shells.

On further rotation of the drum, shafts 21 are gradually retracted and the rolls 24 withdrawn from the cigarette shells and finally are completely withdrawn when the shells reach the lowermost part of the drum 17.

The counter-rolling surface terminates at this point and the finished counter-rolled cigarette shells pass on to the feed band 29 and can be directly delivered therefrom. The surface 30 provided above the feed band prevents any shells from being thrown to the right-hand ort 20 for the shafts 21 rotates over the feed band 29 when the drum is rapidly rotated. a

In the embodiment shown in Fig. 3, the plungers 21 are provided with rolls 24 and a counter-rolling surface 28 is provided as in the arrangement shown in Fi 1 and 2. In this instance however, the s ells 1 are ,led direct to the pockets 18 of the drum through the channel 3 by means of a rake-like implement 2.

In order that the rolls 24 may gradually come into engagement with the counter-rolling surface 28 either this counter-rolling surface is not exactly concentric with the drum shaft 19 as it is in Fig. 1 or else the orifices for the shafts 21 are not arranged concentrically of the disc.

In performing the new method it is immaterial whether the rolls on which the shells with their mouth-piece ends are pushed are rolled around a counter-rolling surface or whether the roll carrier is stationary and the counter-rolling surface is moved around the rolls.
